Summary

A recent study published in the journal Science Robotics found that when a humanoid robot makes mistakes, people become more suspicious and less trusting, especially if the robot is expressive and uses gestures and eye contact. The study used a wearable brain imaging system to measure brain activity and found that the brain regions responsible for monitoring uncertainty and inferring intentions were more active when the robot made mistakes. The study suggests that expressive cues can shift how people perceive a robot’s mistake from a technical malfunction to a social violation.

The numbers tell one story.

When a humanoid robot makes mistakes, people become more suspicious and less trusting. The brain regions responsible for monitoring uncertainty and inferring intentions are more active when the robot is expressive. Oxytocin levels increase, but instead of promoting trust, it tracks with suspicion. The study’s findings suggest that expressive cues can shift how people perceive a robot’s mistake.

The robot’s mistakes are not just technical malfunctions, but social violations.
